Sound recordings

A sound recording, according to the Canadian Copyright Act, includes "a recording fixed
in any material form, consisting of sounds, whether or not of a performance of a work,
but excluding any soundtrack of a cinematographic work where it accompanies the
cinematographic work."

Sound recordings may have multiple copyright protections:

Protection of the recording itself (CD, audiocassette) (held by producer of recording)

Protection of the performance (held by performers on the recording)

Protection of the music/lyrics (held by composers of music/lyrics)

Playing a sound recording in class

Section 29.5 of the Copyright Act allows the playing of a non-infringing sound recording "on the
premises of the educational institution for educational or training purposes and
not for profit, before an audience consisting primarily of students of the
educational institution, instructors acting under the authority of the educational institution or any person who is directly responsible for setting a curriculum for the educational institution."

Copying a sound recording that includes a musical work

Copying a sound recording that includes a musical work for individual personal
use onto a "blank audio recording medium" as defined by the Copyright Act is permitted.
You cannot copy a sound recording for someone else or for any other purpose including
selling/renting out, distributing, communicating to others, or performing the
recording in public. The Copyright Act has established a system of levy fees on
blank media for providing royalty payments to composers, performers and sound recording
producers (s.8). In Canada, the Canadian Private
Copyright Collective is responsible for collecting and distributing private copying royalties.

Using clips, modifying/sampling/remixing

Musical clips
Using clips of a musical sound recording generally requires copyright clearance from
the copyright holders unless you are engaged in non-commercial user-generated content. In Canada, for musical recordings contact
the Canadian Musical Reproductive Rights Agency.

Non-musical clips
Using clips of a sound recording in another work generally requires copyright clearance from the copyright holders unless you are engaged in non-commercial user-generated content.

In addition, some exceptions may apply under the fair dealing provisions.
